Product details


The system can effectively monitor the temperature and thickness of the furnace body on-line, and comprehensively judge the condition of the furnace body and smelting process at any time, so as to realize the high-efficiency process of the furnace.






In the operation of blast furnace, the reasonable distribution of gas flow in the furnace should be strictly controlled, and the excessive development of marginal gas flow should be strictly controlled, which is the basic guarantee to realize high yield, high quality, low consumption and long life. We know that after the new blast furnace is put into operation, the furnace wall from the waist to the lower part of the furnace body is eroded completely in the period of 2.5-3.5 years. In the production process of blast furnace, it is necessary to be able to grasp the changes of blast furnace body and smelting situation at any time, so as to take corresponding technical means, control the slow erosion of furnace body and smelting process, and improve the equipment level of automatic online monitoring technology,


Because of the dynamic change of heat conversion and recovery, the temperature state and charge operation state in the furnace can be determined by analyzing the gas distribution characteristics of the blast furnace (charge distributed on the top of the furnace) section.


The development of heat exchange and recovery processes for heat regulation has been determined in terms of the stability of the potential energy necessary expenditures. Therefore, the dynamics of recovery and heat exchange process and the heat regulation of blast furnace are determined to a certain extent by the airflow distribution characteristics of blast furnace cross section used to distribute the burden on the top of blast furnace.
